Two accessories, a card programmer (CP-l)
and an item counter (IC-l) are available for
use on any model in the 300 Series. The card
programmer is an especially helpful addition
for users that perform repetitive operations.
It is connected in series between the keyboard
and the electronic package and uses standard
8O-step data cards that can be readily punched
by the user for his particular programs. The
item counter proves its value for users that re-
quire item counts, operational step monitor-
ing, and function monitoring. It is connected
to the keyboard, and like the card programmer
can be placed on the user's desk for conven-
ience. Detailed descriptions and operating in-

The \Íode1 300 Calculator is the basic model
in the 300 Series. Operational capabilities in-
clude addition, subtraction, multiplication,
chain multiplications, divisions, reciprocals,
percentages, automatic extensions, weighted
averages. etc. Two independent adders, one on
each side of the keyboard, provide storage and
recall capability. Accumulating switches are
provided for automatic accumulation of entries
and / or multipliers in the dght adder, and pro-
duct or extension accumulations in the left
adder.
All operations, as well as number and deci-
mal input, are initiated by the keys on the key-
board. Display is provided by 5/6 in. high glare-
tiee indicator tubes that display the readout
in conventional form (algebraic sign and nu-
merical value with properly positioned deci-
mal point). t_2
A "clear display" key enables the user to
clear the display without destructing the con-
tents ol the accumulators, etc. A "clear all"

al operational keys lor the functions of log"x
and ex. Both operations are performed instan-
taneously and furnish direct 1O-digit readout
in the display window;the accuracy for log"x
functions is 12 digits, the ex accr:racy is 1l
digits. The addition ol the log lunctions allow
the user to generate logs and exponents to any
base. simplifying calculalions in many areas
of applications. Chain multiplication and di-
vision, using cumbersome numerical values, can
be readily manipulated by using the log and
antilog approach. Techniques for using the log
keys are discussed in the operation section of
this manual and can be readily learned in
minutes. Both simultaneous and non-simul-
taneous operations are available with the Model
320, as well as accessory equipment. Trigo-
nometric keyboards for single keystroke gener-
ation of sine, cosine, arc sine, and arc tangent
in degrees or radians are also available in this
model.
I.5 MODEL 360 ELECTRONIC
CALCULATOR
The Model 360 provides all the features and
functions of the Model 320 plus four storage
registers with capacity for l4-digit numbers
and algebraic signs. Eight additional keys have
been added to the keyboard to furnish random-

access recall and store opeÍations. The..clear
all" function does not affect the registers and
numbers previously put into any storage regis-
ter will remain until a new number is stored.
The ability to store constants, intermediate
answeÍs, oÍ multiple results allows the user to
perform many calculations without re_entering
the data. The Model 360 is available with trig-
onometric keyboards for degree or radian in_
puts. Simultaneous electronic packages are
available with this model.
I.6 MODEL 362 ELECTRONIC
CALCULATOR
The Model 362 provides all the features and
functions ofthe Model 320 and has a keyboard
arrangement similar to the Model 360. The
four extra registerc of the latter are replaced
by 12 registers, each with a 14-digit capacity
(plus sign and decimal storage). Each register
may be used as a storage register or as an ac-
cumulator. When used as storage, any register
may be "split" into two ..halves,,, each with
independent store and recall capabilities. Ca-
pacity of the "half registers,' is six digits, sign,
and full l0-place decimal location. Two key_
strokes are required to command the registers
(i.e., store full and 9). The number keys 0-9,
clear display key, and change sign key are used
to differentiate between the registers.The exe_
cution of the register operation keys prior to
depressing the address key prevents the nor-
mal key functions.
Figure 1-5.l,lodel 362K Keyboard
The Model 362 is available with trigonomet-
ric keyboards for degree or radian inputs.
Simultaneous electronic packages are not a-
vailable with this model.
1.7 TRIGONOMETRIC KEYBOARDS
Six trigonometric keyboards are available in
the 300 Series (320KT or 320KR, 360KT or
360KR, and 362KT or 362KR). Two configu-
rations are available depending on user,s re-
quirements; tlie KT models accept angular in-
put in degrees, the KR models accept angular
inpnt in radians. The keyboards are identical
to the non-trigonometric keyboards with the
exception of four additional keys (SIN, COS,
SIN-1, TAN '1. All trigonometric keyboards
operate with theirassociated standard electron-
ic packages.
Results are readily obtained by entering the
angle, sine, or tangent and depressing the ap-
propriate key. The answer in degrees and frac-
tions is read in the display eliminating the need
for table references and error-prone tedious

\ÍODEL CP.1 CARD PROGRAMMER
. \1 'u<' cP- I Card Programmer is a com-
pact, general-purpose plug-in accessory which
enables automatic calculator operations when
used with any 300 Series Keyboard. It reads
8O-step 2-digit octal program codes, cores-
ponding to keyboard operations, from punch-
ed tab cards.

each terminal of the electronic package (up to
four for a simultaneous electronic package).
The CP-l may be used in conjunction with a
trigonometric keyboard on the same electron-
ic package terminal, but cannot initiate trig
programs under card program control. Exten-
sion cables up to 50 íeet in length may be used
to interconnect the Cp-t with an electronic
package.
The CP-l is enclosed in a cast housing with
START and CONTINUE push button controls
at the top. Bifurcated contacts and a high me_
chanical advantage lever closure mechanism
provide reliable reading of static tab cards.
Built-in electronic circuits are solid-state, and
of plug-in construction. An auto/manual
switch on the side of the programmer enables
the user to examine and verify each program
step when initiating a new program.
Programs are recorded using pre-scored tab
cards, prepared using a port-a-punch and sty-
lus. The sequence of manual keystrokes re_
quired to execute the problem are determined
and recorded. The corresponding program
code bits are sequentially punched out on the
pre-scored tab cards. A ..stop', code provides
the means for entering the variables into a
program.
An excellent library of programs is furnish_
ed free with each CP-1.
1.9 THE MODEL IC.l ITEM COUNTER
The Model IC-l Item Counter is an optional
accessoÍy that can be used with any keyboard
in the 300 Series. It provides the user with the
means for obtaining a ready reference to the
number of addition, subtraction, multiplica-
tion, division, square root, and square opera-
tions, or any combination of these operations
in any calculation. The capacity of the counter
is 10,000 less I (9,999).
Operation is controlled by a series of select-
or switches. When a function count is desired,
the appropriate switch is placed to the up
position. A reset control is provided for re-
setting the counter to zero between calcula-
tions.
The counter has an attached lS-inch cable
that connects to any 300 Series Keyboard that
has been modified with an IC-l mating con-
nector. Connectors are factory installed on
keyboards shipped with item counters, other
keyboards can be returned to the factory for
retrofitting.

2.4 LOCATION OF ELECTRONIC
PACKAGES
Electronic packages, both simultaneous and
non-simultaneous operate efficienfly at room
temperature. Because a certain amount of heat
accumulates in the package when power is ap_
plied, it is advisable to place the unit in a loca-
tion where there is some free air movemenl.
Unventilated storage cabinets, closets, etc. are
undesirable; cases have been known when a
very close environment caused temperatures
inside the electronic package to rise above
130" F. This temperature would present an op-
erating limitation to the equipment and can
cause malfunctions to occuÍ.
2.5 EQUIPMENT INTERCONNECTING
ARRANGEMENTS
Many different hookup configurations are
possible with the 300 Series equipment line.
Figure 2-1 illustrates in block diagram form
some oí the most common configurations. Be_
cause of design parameters, limitations are im_
posed on some configurations. If in doubt
about special arangements not included here_
in, please contact your Wang representative for
further information. Connector shape allows
only one method of mating; note configura_
tion of connectors. Secure connectors with
spring locks.
2.6 SPECIAL CONSIDERATIONS
Keyboard extension cables cannot be placed
in a conduit which is already occupied by an
AC power line. Conduits should be used to pro-
tect extension cables which are subjected to
indefinite exposure outdoors, extreme tropi-
cal conditions of saturation, humidity, and
high ambient temperatures.

Insrullaríon
For multiple-outlet installations, the non-
simultaneous electronic package, or each of
the four output channels of the simultaneous
package, is limited to a tv,/o-tier, three T-
Connector maximum setup for branching to
four regular keyboard outlets.
A maximum length limitation ol 200 feet
should not be exceeded when using extension
cables between standard keyboards (not KTs)
and electronic packages.
The branching maximum is limited to a two
T-Connector, three outlet setup whenever a
CP-l Card Programmer, or a KT Trigonometric
Keyboard is attached. Further. either ol these
items must be connected to a first-tier or pri
mary T-Connector. This rule also applies when
a pnority PT{onnector is used.
Due to power requirements, the extension
cable from the electronic package to the CP-l
Programmer or to tlte KT Trigonometric Key-
board is limited to a 5O-foot maximum length.
Caution must be taken to prevent overload-
ing a channel with more than one KT Trigo-
nometric Keyboard or more than one CP-l
Card Programmer. For maximum safety in con-
trol of outlets, the Ttotlnectors should be
located close to the electronic package.
Using T{onnectors, the keyboard turned
on lirst will go "on line". Displays on the re-
maining outlets will not light up_ In all T-
branched connections, each keyboard user
should establish a courtesy habit of turning off
the keyboard after use.
A priority PT{onnector permits one of
three interlinked keyboards to preempt the
electronic package for immediate use ancl in-
terrupt any unfinished work initiated on an-
other keyboard. The electronic package sup-
ports only one priority keyboard on the first
tierof a PT{onnector. Two additional normal
outlets can be used.
When a CP-l Card Programmer and a KT
Trigonometric Keyboard are used together,
they must be direct11, coupled to lhe elecir.-::-
package.
Four orrtlets are the nrarimu-11 anic-::
available from any one channel of an ele.tro:-
ic package (please remember KT and CP-
restrictions).
A simultaneous electronic package can,l-
ways be substituted for a non-simultaneo:.
electronic package.
When a high trumbered model of electroni:
package is installed, it can accept keyboard: o;
a lower numbered series as well as its ou r
numbered series. A lower numbered electronic
package can operate with a higher numbered
keyboard (except 360K with 320E), but added
key lunctions of higher unit will not be opera-
tive.
Because of design characteristics, a Model 36OK
Keyboard and a Model 320K Keyboard should not be
attached to the same T-Connector. When this condi-
tion exists, the Model 360K Keyboard loses the use oÍ
its extra storage registers. Two Model 360K Keyboards
attached to a T-Connector would function normally.
A Model 360K Keyboard should not be attached
to a Model 320 Electronic Package; erroneous indica-
tions may occur.
2.7 TURN-ON PROCEDURE
After interconnecting the yarious units of
the system, peruse your equipment for power
switches. Place all power switches to OFF.
CAUTtONT
Thc preceding procedure is ex-
tremely important. Damage to
the equipment can result if
power is applied to equipment
with power switches ON.
Connect units that require AC power to ex-
ternal AC power outlet. Three-pronged con-
nectors lor common grounding are provided on
all Wang equipment for your safety.

2.8 TURN-OFF PROCEDURE
Turn-off procedure is simple but important.
Always place keyboard power switch(es) to
OFF before disconnecting keyboards from
electronic packages. This simple pÍecaution
prevents any transistor damage that could arise
from a voltage surge caused by a sudden dis-
connection. Electronic packages can remain
ON without damage. If a CP-l Card program-
mer is used, the keyboard should be discon-
nected before the card programmer. Likewise,
the reverse is advisable for connection policy.
Always make certain that the
keyboard is tumed off before
connecting or disconnecting
equipment. Also, heed turn-on
order; electronic package first,
then the keyboard(s).
